Objective To explore the indication,technique and complications of Snodgrass operation in hypospadias repairment.Methods From Sep.2005 to Nov.2006,22 boys from 2 to 18 years old with hypospadias were treated with Snodgrass modification.The procedure was performed in 16 patients as a primary repairment and in 6 patients as the 2-stage repairment.The entire length of the urethral plate was incised along the midline in primary repairment,and the skin flaps and residual urethral plate were incised in the 2-stage repairment.The length of neourethra was from 1 to 10 cm.The neourethra was tubularized over a F 6 or F 8 catheter.The urethral stent was removed in 10 to 14 days pos-toperatively.Results Of the 22 patients,18(81.8%) required no other surgery as the repairment provided a normal appearing penis(straight,terminal meatus, cosmetics) without complications.Fistul aoccurred in 4 patients(18.2%) and meatal stenosis in 1 patient.Conclusion Snodgrass operation creates a vertical slit-like neomeatus.The procedures restores good function and normal appearance to the penis.

Objective To compare the curative effects of CT-guided ethanol injection and lauromacrogol injection into the sac cavity in treating ovarian endometriosis cysts. Methods A total of 86 patients with ovarian endometriosis cyst were enrolled in this study. The patients were divided into ethanol group (n=44) and lauromacrogol group (n=42). Under CT guidance, injections of ethanol or lauromacrogol into the sac cavity of ovarian endometriosis cysts were respectively performed for the patients of both groups. The patients were followed up for six months, and the curative effects and the complications were analyzed. Results Six months after the treatment, the cure rates of ethanol group and lauromacrogol group were 95.50%and 92.86%respectively, and no statistically significant difference in cure rate existed between the two groups (P>0.05). The preoperative serum CA125 levels of the ethanol group and lauromacrogol group were (48.42±23.68)μg/L and(49.21±22.83) μg/L respectively, and the post operative ones were (23.56±5.89) μg/L and (25.49± 6.10) μg/L respectively; the differences between the preoperative data and the postoperative data were statistically significant in both groups (P<0.05), although the differences in serum CA125 levels between the two groups were not significant (P>0.05). The incidence of postoperative complications in the lauromacrogol group was obviously lower than that in the ethanol group (P<0.05). The cure time in the ethanol group was shorter than that in the lauromacrogol group, although the difference was not significant after six months. Conclusion For the treatment of ovarian endometriosis cysts, CT-guided lauromacrogol injection into the sac cavity has reliable curative effect. Compared to ethanol injection, injection of lauromacrogol is safer and has fewer adverse reactions. Therefore, this technique should be recommended in clinical practice. Serum CA125 can be used as an indicator for the evaluation of curative effect.

Objective To explore the clinical utility of fluorescence in situ hybridization (FISH) urine test as a non-invasive method for diagnosing the upper urinary tract urothelial carcinoma (UUTUC).Methods Urine specimens from 30 consecutive patients with UUTUC were analyzed by means of FISH and cytology.Ultrasonic and CT were also used to analyze urine specimens from the study group.Urine specimens from 30 patients with other diseases were also analyzed by means of FISH and cytology in order to compare the specificity.Results The sensitivities of FISH,cytology,CT and ultrasonic were 87％,37％,90％ and 43％.The specificity of FISH and cytology were 97％ and 93％.The sensitivity between FISH and MMCT were compared and they were not statistically significantly superior to ultrasonic and cytology.FISH and cytology were compared and no specific statistical significance was found.The positive and negative predictive value for FISH was 96％ and 88％.For cytology it was 85％ and 60％.Conclusions FISH analysis is a useful ancillary test in the detection of UT-TCC with excellent sensitivity and specificity.It provides a more reliable and less invasive approach to diagnosis and postoperative follow-up for UT-TCC.

Objective To investigate the efficacy of retroperitoneal laparoscopic heminephroureterectomy for duplex kidney anomalies.Methods Retroperitoneoscopic heminephroureterectomy was performed on nine patients, six males and three females.The average age of the study group was 37 years ( range 13 to 58).Seven cases had anomalies on the upper kidney pole, two cases had anomalies on the lower kidney pole.Five anomalies were on the left side, two were on the right side and two were in bilateral sides (one special case had three ureters on the left side and two ureters on the right side ).Three cases complained of flank pain; two cases were found hydronephrosis by physical routine examination;Three cases complained of flank pain and fever; one cases complained of hematuria and kidney atones.All the cases were preoperatively diagnosed by color doppler ultrasound, MRU, IVP or CTU.Retroperitoneal laparoscopic heminephroureterectomy was performed on all patients.The operation time, blood loss, hospital stay, intraoperative and postoperative complications and efficacy were observed.Results All the retroperitoneal laparoscopic procedures were successfully completed.No intraoperative complications were found.The average operation time was 87 min (range, 65 to 125).The average blood loss was 112 ml (range, 30 to 600).The recovery times of intestinal function was 1.6 days ( range, 1 to 3 ).The average postoperative hospital stay was 7 days (range, 5 to 12).The syndrome disappeared and kidney function was normal at a mean followup of 18 monthes.Conclusions Retroperitoneal laparoscopic surgeries for duplex kidney has the benefits of being minimally invasive, fewer complications, quick recovery and certainty of efficacy.Retroperitoneal laparoscopic surgeries can be considered as a first operation method to treat duplex kidney anomalies.

AIM: To investigative the inhibitory effects of Paecilomyces cicadae polysaccharide (PcPS) against HBV in vitro, and the effects on the Toll like receptor 4 (TLR4) mRNA expression in HepG2.2.15 cell strain. METHODS: HepG2.2.15 cell strain was co-cultured in vitro with PcPS in different concentrations, and lamivudine (LMV) was applied as positive control. MTT assay was employed to detect the cytotoxicities of PcPS in vitro, when the HepG2.2.15 cells was used as target cells. The effects of PcPS on the secretion of HBsAg and HBeAg were assayed by ELISA method. Fluorescence quantitative-PCR (FQ-PCR) was used to detect the inhibitory effects of PcPS on the content of HBV-DNA and TLR4 mRNA in HepG2.2.15 cells. RESULTS: The inhibitory effects of PcPS on the HBsAg and HBeAg were observed and the maximum inhibitory ratio up to 44.8% and 31.0%, respectively. The same inhibitory effects of PcPS on the HBV-DNA replication and TLR4 mRNA expression in HepG2.2.15 cells were also found. CONCLUSION: A certain concentration of PcPS significantly inhibits HBV replication in vitro.

OBJECTIVE:To provide reference for promoting the prior usage of essential medicines and scientifically selecting of antitumor medicines in the national and local drug reimbursement list. METHODS:Entering the Human Resources and Social Se-curity Bureau websites in 10 cities(Beijing,Shanghai,Guangzhou,Nanjing,Wuhan,Xi’an,Chengdu,Shenyang,Jinan and Gui-yang),drug reimbursement list was downloaded to statistically analyze the containing of antitumor medicines(including 24 essential medicines). RESULTS:In antitumor medicines,there were 5 cities with more than 100 varieties,of which Shanghai had 255 vari-eties,which was far more than other cities;the numbers of medicines in class A were near 30 in all the cities except Beijing(67 va-rieties),and the number of class B was highest in Shanghai and lowest in Beijing. All the drug reimbursement lists in 10 cities con-tained 24 antitumor essential medicines,however,the classification was different according to the dosage forms,among which, parts of formulations of cytarabine(injections),doxorubicin(injections),busulfan (often release oral dosage forms),fluorouracil (often release oral dosage forms,injections),cyclophosphamide(often release oral dosage forms,injections),methotrexate(often release oral dosage forms,injections)and cisplatin were classified as class A medicines in all cities;oxaliplatin(injections)and pa-clitaxel (injections) were classified as class B medicines;busulfan,fluorouracil,cyclophosphamide and methotrexate were classi-fied as class B in Shanghai only. CONCLUSIONS:There are some differences in the distribution of antitumor essential medicines in drug reimbursement list in each city,the varieties in developed cities are relatively more,and developing cities are less. It is sug-gested to consider the tumor epidemiology characteristics and economic situations,reasonably select antitumor essential medicines into drug reimbursement list and reasonably adjust the proportion of class A and B to ensure the basic medication and drugs’reim-bursement.
